My problems with this are solved! Thanks.
I do have version 1.3.5. that is why I responded to this thread. But somehow I did have a difference between the tpl_header.php in my template and the one from common in the default template.
As soon as I started fresh with the tpl_header.php from the default template (copied into the common in my template) the suggestion about deleting the
<br class="clearBoth" /> works perfectly without my NavMain dissapearing! I am now of course also checking the other tpl files in mytemplate common ......
The solution for the logo is a different one than mentioned in
http://www.zen-cart.com/forum/showthread.php?t=45734 That is about horizontal alignment and I was looking for vertical alignment of the logo.
I did find the code in my css:
#logo, .centerBoxContents, .specialsListBoxContents, .categoryListBoxContents, .centerBoxContentsAlsoPurch, .attribImg {
float: left;
}
Whatever I tried with this, it never vertically aligned only the logo the desired way (vertical middle of Logo Wrapper). It e.g. perfectly aligned my catagorie pictures mentioned on the mainpage and a lot more, except for the logo.
I finally added the following code to my css right below the above code and that did the trick:
#logo {
padding: 1.5em;
}
